ComfyUI - 使用 ComfyUI 部署与测试 FLUX.1 图像生成模型教程

前言

FLUX.1 是由 Black Forest Labs 推出的文本到图像生成模型，已成为 AI 绘画领域的高品质模型。该模型由 Stability AI 的前核心成员开发，具备强大的生成能力和高质量的图像输出。目前，Flux 的相关模型：

Flux & AE 模型：https://huggingface.co/black-forest-labs/FLUX.1-dev
CLIP 模型：https://huggingface.co/stabilityai/stable-diffusion-3-medium

FP8 模型地址：https://huggingface.co/Kijai/flux-fp8/tree/main

安装 HuggingFace 下载工具，使用镜像下载速度明显加快：

export HF_ENDPOINT="https://hf-mirror.com"
pip install -U huggingface_hub hf-transfer

下载 HuggingFace 脚本，如下：

huggingface-cli download --token [your toekn] black-forest-labs/FLUX.1-dev --local-dir FLUX.1-dev --include "flux1-dev.safetensors" 
huggingface-cli download --token [your toekn] black-forest-labs/FLUX.1-dev --local-dir FLUX.1-dev --include "ae.safetensors"
huggingface-cli download --token [your toekn] stabilityai/stable-diffusion-3-medium --local-dir stable-diffusion-3-medium

下载之前需要申请权限，Token 地址来源于：全部勾选即可生成。

其中，完全版是 FP16 的版本 flux1-dev.safetensors，大约 23G，即：

FLUX.1-dev/flux1-dev.safetensors 
bypy upload flux1-dev.safetensors /stable_diffusion/flux_data/flux1-dev.safetensors

AE 模型：

FLUX.1-dev/ae.safetensors

CLIP 是两个模型：

stable-diffusion-3-medium/text_encoders/clip_l.safetensors
stable-diffusion-3-medium/text_encoders/t5xxl_fp16.safetensors

将 Flux 的相关模型，放入相应的位置：

ComfyUI/models/unet/flux1-dev.safetensors
ComfyUI/models/vae/ae.safetensors
ComfyUI/models/clip/clip_l.safetensors
ComfyUI/models/clip/t5xxl_fp16.safetensors

所有的AI设计工具，模型和插件，都已经整理好了，👇获取~

为了帮助大家更好地掌握 ComfyUI，我在去年花了几个月的时间，撰写并录制了一套ComfyUI的基础教程，共六篇。这套教程详细介绍了选择ComfyUI的理由、其优缺点、下载安装方法、模型与插件的安装、工作流节点和底层逻辑详解、遮罩修改重绘/Inpenting模块以及SDXL工作流手把手搭建。
